Euglena viridis

Unicellular eukaryotes living in freshwaters, capable of feeding autotrophically and heterotrophically.

Paramecium caudatum

Common ciliated eucaryotic unicellular organisms widespread in freshwaters.

Animal and plant cells, cellular organelles

Eukaryotic cells contain a number of organelles.

Bacteria (spheres, rods, spirals)

Bacteria occur in a wide range of shapes, including spheres, rods and spirals.

Jellyfish

Jellyfish are free-swimming marine animals, a species of Cnidaria, the most ancient group of Eumetazoans.

Photosynthesis

Plants are capable of converting inorganic substances (carbon dioxide and water) into organic sugar.

Tardigrade

Tardigrades can survive in extreme environments, they can even stay alive in outer space.

The structure of prokaryotic and eukaryotic cells

There are two basic cell types: prokaryotic and eukaryotic cells.

Viruses

Viruses consist of protein and DNA or RNA, they reprogram infected cells to produce more viruses.

Comparison of edible and poisonous mushrooms

Certain mushrooms are poisonous and can be fatal for humans when consumed, while others are edible and used widely in cooking.

DNA

Carrier of genetic information in cells.

Meiosis

Our gametes are haploid cells produced from diploid cells by meiosis, a special type of cell division.

Mushrooms

A mushroom is the fleshy fruiting body of a fungus, made up from hyphae.

Organisation of genetic material

Eukaryotic cells with nuclei measuring only a few micrometres may contain nearly 2 metres of DNA, coiled multiple times.
